NEDG: Efficient Protocol Design for RFID Systems

NEDG: RFID系统的高效协议设计互联网通过将众多计算机连接在一起，彻底改变了世界。现在，人们正在见证另一场革命，数以十亿计的实物物品，如衣服、文件夹、书籍和其他物品与电脑相连。由于支持无线射频识别（RFID）技术，这一愿景正在成为现实，该技术允许读取器从附着在物品上的廉价标签上远程读取信息。为了使这项技术能够在实际应用中读取大量标签，设计有效的RFID通信协议至关重要。对当前RFID研究的分析表明，在高层数据消费者和低层无线通信工程师之间存在二分法——低层可见的大部分信息对高层是隐藏的。这种受限的接口导致了与效率和安全相关的问题。为了解决这个问题，本计划旨在采用跨层设计方法，让高层数据用户可以利用更多从底层暴露出来的信息来解决现有的问题。知识价值：该项目将设计协议和算法，为非常相关的库存控制应用提供更好的性能，帮助RFID行业的研究人员了解“跨层设计”的力量，并指导RFID通信协议的设计，使相关信息可用于高层。更广泛的影响：这项工作可能会对RFID通信协议的工业标准产生影响。该计划亦会将研究与教育结合，向学生介绍RFID的算法及系统设计。

NEDG: Efficient Protocol Design for RFID SystemsInternet revolutionized the world by connecting numerous computers together. Now people are witnessing another revolution when billions of physical items, such as clothes, folders, books, and other items are connected to the computers. This vision is becoming a reality, thanks to the supporting Radio Frequency Identification (RFID) technology, which allows a reader to read remotely information from an inexpensive tag attached to an item. To enable this technology for reading massive tags for realistic applications, it is crucial to design efficient protocols for RFID communication. The analysis to the current RFID research shows that a dichotomy exists between the high layer data consumer and the low layer wireless communication engineer -- most of the information visible to the low layer is hidden from the high layer. This restricted, throttled interface results in efficiency and security related problems. To solve the problem, this project aims to apply cross-layer design methodology so that high layer data users may harness more information exposed from below to solve the existing problems.Intellectual Merit: The project will design protocols and algorithms that deliver better performance for very relevant inventory control applications, help researchers in RFID industry to understand the power of "cross-layer design", and guide the design of RFID communication protocols to make relevant information available to the high layer.Broader impact: This work will potentially have an impact in the industrial standard for RFID communication protocols. The project will also integrate research and education by introducing algorithm and system design in RFID to students.
